PORTABLE HOLDER FOR ELECTRIC LAMPS.

Specification of Letters Patent Patented Dec. 26, 1916.

To all 'whom it may concern:

Be it known that I, Revues B. BENJAMIN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful. Inipro vcnrentsin Portable Holders for Electric Lumps of which the following is a full, ole 'r, onncise, and exact description, reference being bad to the accompanying druwing, forming a part of this specification.

My invention relates to por able holders for electric lamps.

It is one of the objects of my invention to provide a gasprool portable lump holder of such a mature that all danger of access of a circulation of gas to the neighborhood. ol' {1 lamp is removed so that the light may be safely used in the presence of gases.

is a further object of my invention to provide such a device in which the glass globe is protected with a minimum amount elf-obstruction to the light rays.

It is still a further object of my invention to provide a fixture of the sort described which is economical to manufacture, simple in its construction and adaptable to a great variety of uses.

Additional objects and advantages will be apparent from the following specification taken in connection with the appended claims.

A holder constructed in accordance with my invention 1 have, described, by way of example, in the. following specification and illustrated in the accompanying drawings, in which- Figure 1 is a side elevation; Fig. 2 is a lan view of thesocket from below; Fig. 3 1s a. cross sectional view (enlarged) taken on the line 3-3 of Fig. 1 looking in the direction of the arrows; Fig. 4 is a similar view taken on the line 4-4. of Fig. 3, looking in the direction of the arrows; and Fig. l) is a cross sectional View (reduced) showing a part of the socket, the section being taken on the lino 5-5 of Fig. 3, looking in the direction ol the arrows.

Referring to the drawings, the device is means of a wooden handle 1 which is provided with an a erture 5 for the entrarce teed wires 6. hose wires lead to a, pm r 0i binding posts 7 electrically connectcil will on ordinary lump shell 8 as will herein after he described.

TLQ Shel 8 is seated 1111 a porcelain base 9 and is secured therein by a pair of screws 9", the heads of which are soldered or cemented in suitable recesses in the porcelain base. The shell 8 and base 9 form a socket for the reception. of an incandescent'lamp 10. The base 9 of this socket is providedynear the top thereof with a shoulder or flange 11 arranged to rest on a corresponding shoulder 12 formed in the top 01. the wooden handle 4 which is enlarged to ncconnnodatc the socket. Any rotation of the socket with respect to the handle is prevented by a projection 13 on the socket which lits into a corresponding recess in the handle.

The circular top of the sockets flange 11 is made fairly wide and is in substantially the same plane with the top of the handle 4, forming a seat 1l for a gasket 15 made of asbestos or other suitable yielding material.

The lamp is inclosed by a glass globe 16 which is screw-threaded at its lower and open end to engage a screri'-threo.der shell 17 secured to the handle =1 by screws passing through downwardly projecting lugs formed on the shell. The shell is so positinned that when the globe 16 is screwed into place it is drawn down onto the gasket 15 and the latter is, by the twoopposing forces, clamped tightly between the globe and the socket with the result that a gas-tight joint is provided.

In electrical. contact with the shell 8 of the socket and the central contact 19 thereoi are screws 20 which pass through plates 21 and clamp them, in suit-able recesses, against the porcelain base 9 of the socket. Through these plates pass the binding screws 7, their inner ends extending into blind recesses in the porcelain base. It will be seen that there is no direct puss-ageri 'cy from the binding posts to the interior of the socket. The screws 20 clamp the plates 21 tightly in place and gas-tight connections are consequently provided. If desired solder or cement may e applied where the screws 20 protrude throu 'h the plates 21. It will thus be apparon that the socket and globe 15 form a chamber for the lamp into which no gas can enter and the device may, accordingly, be used in many circunistances which, owing to the presence of explosive gases, would preelude the use of the ordinary light.

To protect the glass globe a guard is provided cmnprising a. diagonal lacing of metal ribs Each rib is formed at its top with a notched end 23 to engage a corresponding slot in .a spider 2% iorn'iing' a spacing member which protects the top end the globe. At their opposite ends the ribs was through slots in a ring 5 also 'ioru'iiuc a spacing member and are riveted into a cup member 26 which is secured to the ring 25 by having its edge turned over onto the latter. The upper ends of a pair of ribs engage the same notch in the spider and the opposite ends ol? that pair enter the slots occupied by the next preceding,- and next succeeding ribs respectively. This construction gives a lacing effect that provides a guard of great lateral rigidity capable of resisting forces tending to distortion of the ribs. And as the ribs are arranged cdgcwise to the lamp there is a minimum obstruction to the light rays.

The guard is secured to the handle by means of the screws 18. lla vonerslots 27' are formed in the cup member 26 and slip over these screws and when the latter are tightened the guard is held firmly in place.

A hook 28 is prmided by means of which the light may be hung in any place desired. This hook is hinged to the spider 2 by means of a. lug 29 formed on the spider and bent over to embrace the hook as shown in Fig. 1. Thus the hook may be turned down flat against lhc guard when not in use. A projection 30 on the hook engages the guard when the hook is raised to substantially vertical position and prevents its movement beyond such point.

ll. will be apparent that changes may be made in the forn'i, construction and arrangement of the parts without departing from the spirit of my invention or exceeding the scope of the appended claims, the form of the invention herein disclosed being merely one preferred embodiment thereof.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
